I invite colleagues to open debate around the issues raised in my presentation, both those relating to research and to practice.

Thank you for your presentation Paula.  It is interesting to learn about your research, so close to home!  What do you think about the sequestration rates and potential of totara versus kanuka?

Hello Susan, yes my research is quite local. However, in terms of Kanuka and Totara, the carbon content in early stages differs. As both species establish in different ways they are both necessary for our restoration plantings. Having more Totara increases the carbon content, and Kanuka is a great pioneer plant. Both work well in combination. I believe that both species provide important outcomes in our landscapes and biodiversity but Totara will in good conditions, sequester more carbon.

Thank you Paula.  In your plantings is kanuka ever used as a nurse plant for totara?  Or does totara survive well without help from nurse plants.
I have seen totara establishing incredibly well in gorse in western Southland.

Hi Susan, It is fascinating to see how gorse as a nurse plant. In places like Hinewai and Southland, this works quite well. My results did not show a significance between using gorse or other native species as a nurse plant in the Southern Port Hills (where rainfall can be lower). It did show significance in the carbon content if we plant Totara at the edge and only when deer is controlled. My research made me see that there is a balance between pest control and soil moisture content for carbon. I guess there is lots more to it!
